1. An aluminum air-cooled engine cylinder head for asingle cylinder, 2-stroke engine is to
be die-cast. The overall diameter of the cylinder headis 101.6 mm. If the projected
plan area of the runners and gating system is 100 mm2and the casting pressure is 10
MPa (1500 psi), what minimum locking force is requiredfor the die-casting machine in kN.
